Signal encoding device and method therefor

TL;DR: In this article, the authors proposed a method to enhance the encoding efficiency by removing the characteristic or correlativity of a signal by LPC(linear predicted coding) analysis or pitch analysis to the signal waveform of a time base prior to orthogonal transformation in an encoding using OTC.
Patent

Signal decoding apparatus

TL;DR: In this paper, a decoder for reproducing information from an encoded signal that has been frequency-domain transformed by a transform conversion circuit in response to audio signal samples grouped into time-domain blocks based on selected block time lengths, includes a reverse conversion transformation circuit that groups the frequencydomain transfer coefficients into transform blocks.

Apparatus and method of generating waveform, and decoder

TL;DR: In this article, the amplitude, phase and frequency of a sine wave to be generated are calculated on the basis of a feature amount s1 delivered to a feature amounts detecting means 2, and are transmitted to an initial setting means 3.
Patent

Audio signal reproducing device

TL;DR: In this paper, the authors used a semiconductor memory as a storage medium for audio data which are compressed and encoded with high efficiency to reduce the size and weight of a device main body.
Patent

Method and device for retrieving information

TL;DR: In this paper, a speaker retrieval device is proposed to retrieve a speaker of encoded speech data which is recorded in semiconductor storage device inside an IC recorder, where an information receiving part reads the encoded speech and a speech decoding part decodes the encoded data.
